WINDOW-CONTROL 1\tlIECIEIIANISll/I.

Application led May 22,

Tpo all 'whom 'it may concern: j

Be it known that I STANLEY W. N renonsoN, a citizen of the United States of America, residing at Toledo, in the county of Lucas and State of Ohio, have invented certain new and useful Improvements in VVin'dow-Control Mechanism, of which the following is a specification, reference being had therein to the accompanying drawings. This inventipn relates to window control mechanism and more particularly to control devices for the sliding windows of vehicles. The invention consists in the structural features and arrangement of parts hereinafter fully described and illustrated in the accompanying drawings, wherein:-'

Figure 1 is an interior view of an automobile door equipped with the improved mechanism;

Figure 2 is a view showing said mechanism as in Figure 1 but to an enlarged scale. Figure 3 is a vertical cross section on line 3 3 of Figure 2;

Y Figure l is a cross section on line 4-4 of Figure 2;

ln these views the reference character A designates an automobile door having in its upper portion the window opening B and provided with a closure for said opening having the nature of a vertically sliding glass plate C. The lower portion of said dooris formed with a well or chamber D into which said window member is lowered in its open positions. .Within the chamber D is arranged a counterbalance arm E pivoted at E upon one ofthe uprights A of the door and carrying at its free end a roller E2 which is urged into constant contact with the lower edge of the plate C by a coil s ring F. G is a control rod for the closure attached to the latter adjacent the lower edge thereof and upwardly extending adjacent the uprights A so as to be accessible. Said rod is provided upon its upper end with a handle H which is accessible within the openingB in all ositions of said closure. Itis desired to uti ize the rod G as a latch control element as well as an actuating member for the plate C and to this end there is secured to one extremity of the customary channel I engaging the bottom edge of said plate a bracket J formed with a bearing K wherein the lower end of said rod is journaled. helative vertical movement between the rod G and closure may be prevented by 1922. Serial No. 562,871.

providing upon said rod any suitable abutments coacting with the bearing K, as for example the nuts K above and below said bearing. Said rod is integrally formed with a rib L, wherein is formed a series of notches M which' through rocking of the rod may be selectively engaged with a tooth member N mounted upon the uprights A', whereby the closure ma be held in substantially any desired posltion of vertical adjustment. A spring O coiled upon the lower end of sai'drod coacts with the bracket J to urge a rotation of ,the rod G, such as to normally engage the tooth N by one of the notches M of said rod. Rocking the handle H away from the plate C from one to the other of the dash line positions shown in Figure l serves to unlatch the closure and a subsequent upward or downward pressure upon said handle effects the desired vertical shifting of the closure.

It is preferred to dispose the rod G within a tubular metal trim stick P which is mounted upon the uprights A within the opening B being secured in place by screws P or other suitable means. Said trim stick is slotted, as indicated at R, -:from end to end to permit the handle H to project and to coact the necessary angular and vertical movement. In the disclosed embodiment of the invention the tooth N has the natureA of a tonguef struck out from the lower end of said trim stick, as is best seen in Figure 4.

The trim stick P -in addition to' concealing the control rod G functions also to some extent as a guide member for said rod.

What I claim as my invention is 1. In a window control mechanism, the combination with a sliding closure for a window opening, of a control rod for said closure extending upon the latter in the direction of movement thereof and rotative to exercise a latch function, a latch element carried by said rod substantially co-extensive therewith and a fixed latch element engageable by said latch member through rocking of said rod.

2. In a window control mechanism, the combination with a sliding clesure for a window opening, of a control rod extending upon said closure in the direction of movement and rotative upon the closure to exeroise-a latch function, a rib integral with said rod and substantially co-extensive therewith, notched to form a latch member and a stationary latch" elementrselectively engageable by 'the notches of said rib through rotation of the rod.

3. In a Window control mechanism, the combination With a sliding closure .forca Window opening, and a chamber receiving said closure in its open positions, of a control member for said closure carried thereby and elongated thereupon in the direction of travel thereof to be accessible'within said opening in all positions of said closure, and latch means upon said control member sub-` stantially (1o-extensive therewith, and a coacting stationaryv latch member disposed Within Said chamber. v i

4. In a Window control mechanism,V a member having a Window opening, a sliding closure for said opening, a chamber adjacent said opening receiving said closure in,

the open positions thereof, a latch member Within said chamber stationary relative to said closure, and a latch member upon the closure Yrotatively engageable with said stationary latch member and elongated in the direction of travel' of the closure for selective engagement with the stationary latch member in a plurality of positions of the closure. l

5. In a Window control mechanism, the combination with a sliding closure fora mounted and notched to exercise a latch function in a plurality of positions, and a coacting stationary latch element.

6. In a Window control mechanism, the combination with a sliding closure for a Window opening, of a control rod extendin upon said closure in the direction of trave thereof, said rod being notched and rotatively mounted to exercise a latch function in a plurality of positions, a co-actin stationary latch element, and means resiliently acting upon said rod to urge engagement thereof with said stationary element.

7. In a Window control mechanism, the combination With a sliding closure for a window opening, of a control rod for said closure extending upon the latter in the vdirection of movement thereof and rotative STANLEY W. NICHOLSON.
